[feature]add patch_boot_image

[Ruan8907]

Hello Wild KSU team,
I would like to suggest adding a function similar to patch_boot_image, as seen in tools like APatch, directly into Wild KSU. This function would allow automatic patching of the boot.img, making kernel tweaks easier, especially on older devices and kernel 4.14, which are still widely used.
Expected benefits:
Support for older devices that no longer receive official updates.
Simplified patching without relying on external scripts.
Improved compatibility with kernel 4.14 while maintaining stability.
It would be great if this function could be added optionally, keeping the current workflow intact for users who do not need this feature.
Thank you for your continued work on the project, and I hope this suggestion is considered.
